SHOE-POLISHING MACHINE.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed December 10, 1919. Serial No. 343,775.

T 0 all whom it may concern:

Be it known that I, JosnPH HENRY KARP, a citizen of the United States,residing in the city of New York, borough of Manhattan, county and Stateof New York, have invented a certain new and useful Shoe- PolishingMachine, of which the following is a specification.

This invention is a shoe polishing machine, and, speaking generally, theobject of the in.- vention is a machine of the character specified whichwill automatically polish shoes, and the like, in an expeditious,thorough, economical and generally eflicient manner.

Shoe polishing machines have heretofore been suggested, but theirstructures have been so complicated and their cost so excessive, whichdisadvantages, coupled with the inefficiency of operation of themachines, have precluded their commercial use..

Among the important features of the invention, though not the exclusiveones, may be mentioned the manner of mounting and operating the cleaningand polishing brushes, the means for automatically feeding the polishingmaterial to the brushes, the mechanism for operating the brushes andassociated devices and the manner of controlling, by means of a coin orsimilar member, the motor for driving the various mechanisms inherent inthe machine as a whole.

The driving mechanism is preferably coin controlled, thoughthisjfeature, when the machine is used in certain environments may bedispensed with.

Features of the invention, other than those specified, will be apparentfrom the hereinafter detailed description taken in conjunction with theaccompanying drawings.

In the accompanying drawings, I have illustrated different practicalembodiments of the invention, but the construction therein shown is tobe understood as illustrative only, and not as defining the limits ofthe invention.

In the drawings, Figure 1 is a plan View of the machine. I

Fig. 2 is a sectional side View; a

Fig. 3 is a sectional end view;

Fig. i is a plan View of the cam releasing and electric switchmechanism;

Fig. 5 is an end view of the mechanism shown in Fig. 4;

Fig. 6 is a plan view of a modification of the machine; and, I

Fig. 7 is an end view of said modification.

Referring to the drawings, 1 is a casing within which the operatingmechanism is housed, and 2 a coin box of any desired mechanical type,having a shaft v3 extending downwardly through the top of casing 1 to abearing bracket l. Keyed to shaft 3 is a rocker arm on which is mounteda releasing pawl 6. The bearing bracket 4 carries a cam 7 upon which thereleasing pawl 6 rides, and which releases a rocker arm 8 through themedium of pin 9, for the purpose herein after described. Arm 8 isloosely mounted upon shaft 3 and is returned to'its original position bymeans of a suitably mounted spring. A connecting rod 10 connects the arm8 .with a stop pawl 11 supported on bracket 12, see Fig. 2, the end ofwhich pawl rides on a stop cam 19 Pin 13, carried by the connecting rod10, actuates the electric switch pawl 14: which has integral therewiththe bus-bar 14: of the electric switch 15.

The electric switch pawl 14: is supported by a bracket 16. An arm 17which is keyed to electric switch pawl 14L rides on the switch releasingcam 18 for thatpurpose. .A shaft '20 which is free to rotate in bearings21 and 22, see Figs. 2 and 3, has keyed thereon a worm wheel 23, a cam24;, the stop cam '19, the switch releasing cam 18and a foot operatingcam 25.

A worm 26, meshing with the worm wheel 23, is keyed on shaft 27 itsbearing being part of the bearing 21. -The opposite end of shaft 27 haspositioned thereon a gear 28 which meshes with a spur gear 29 on the"drive shaft of electric motor 30. A lever 31, carried by a pivotbracket 32 has thereon a cam roller 33 which-rides on cam 24%. A pushrod 34, supported in bearings 35 is connected to lever 31 by means of apin 36 which operates in the slot 36 formed in one end of said lever,the purpose of which is to prevent undue friction or binding incident tothe movement of said lever and push rod. A spring 37 is fastened to theend of lever 31 in order to keep the roller 33 in engagement with thecam surfaceof thecam 24:, and which also serves the function of pullingpush rod 34 back with it.

Pawls 38 arein mesh'with ratchet gears I 39, which have a female screwthreaded portion to fit the screw threaded stems on the plungers 40.These plungers, as clearly appears from Fig. 2, operate in the bottlecontainers 41 may be filled with the paste by moving the screw plug 41,said containers having distributers 42 attached thereto, which serve todeliver the paste to v the brushes 58. Containers 41, plungers 40, andratchet gears 39 are supported by brackets 43. A bracket 44 has pivotedthereto a lever 45, and the latter carries a cam roller 46, which isactuated by the cam 25. V The lever 45 is slotted on one end in order toallow a free forward movement of a foot piece 47 to which it isattached, said foot piece having sliding movement in the grooved portionof a bracket 48 for that purpose.

The shaft of motor 30 has mounted thereon' a bevel gear 49, meshing withbevel gear 50, which drives a pinion gear 51, both of which latter gearsare keyed to shaft 52. Pinion gear 51 meshes with a gear 53 on a shaft54, which, in turn, meshes with gears 55 which are centrally pivotedabout the gear 53 by means of pivot arms 56. Shaft 57 to which the gears55 are keyed runs freely in the pivot arms 56, the upper ends of saidshafts having attached thereto polishing brushes 58.

The shafts or spindles 57 are thus supported by the arms 56 for. bodilypivotal movement about the common axis of the shaft 54 and arepreferably normally impelled in a direction toward the shoe support 47by means of a pair of springs 56 shown best in Figs. 2 and 7. Eachof'the springs 56 is-secured to one of thelower arms 56 at one of itsends and at its other end is anchored the upstanding web which supportsthe bracket 48 of the shoe support. The brushes will accordingly beautomatically maintained by the springs 56 in a position to cotiperatewith the shoe resting upon the support 47, but said springs will permitthe brushes to retract slightl to compensate for shoes of differentsizes and to permit of variations in the longitudinal cross sections ofthe shoe as the shoe is moved back and forth between said brushes duringthe polishing operation. 7 7 r n Figs. 6 and 7, which show amodification of the invention, like numerals represent like parts inFigs. 1, '2, 3, 4 and 5. In this modified construction, a collar 59 isinserted between the cam 25 and the cam 24 as a substitute for theswitchthrow out cam 18 and the stop cam 19 and an electric plug 60 and wire 61are employed instead of the construction as described From the foregoingdescription of the mechanism, its operation w ll be readily understood,but it maybe described briefly, as'follows Y ,When it is desired tooperate the machine,

' acoin of predetermined denomination is in- The coin makes a mechanicalconnection with the operating parts in said box thereby permitting shaft3 to be rotated by the hand lever 2., said'shaft acting upon the arm 5,pulling the arm 8 backward, thus releasing the pawl 11 from the cam 19.During the 7 drives the worm wheel 23, mounted on the shaft 20. Cam 25being fast on the shaft 20 will also rotate, and the cam action of saidcam upon the roller 46 will pull the lever 45 backward moving the footpiece '47 forwardly between the brushes 58. The cam 24 has also comeinto action, being on the same shaft, with the worm wheel, the surfaceof which acts on the roller 33 pushing the lever 31 in such directionthat the action of the pawls 38 on the ratchet gears39 will advance theplunger 40 upward by means of the screw threaded stems 39 thus forcingthe polishing paste through the. distributors 42 upon the surface of thebrushes 58. These brushes are rotated when the motor 30 is operated,through the medium of the train of gears 50, 51, 53 and55. The brushes58 being pivotally mounted on arms56, and being under light springtension, operate with uniform pressure upon the shoe, as the footsupporting member 47 reciprocates between them. The cam 25 makes onecomplete revolution to shine both shoes; there being a pause or dwell inthe cam action to allow for the shiftbackward, whereupon the connectingrod 10 is pulled forward. Thepin 13 will then be retracted from theelectric switch pawl 14', allowing the lever 17 to which it is attachedto be thrown outward by the action of the cam 18, thus breaking thecircuit and stopping the machine.

To operate the modified form of machine,

shown in Figs. 6 and 7, the plug 60 on elec-.

tric wire 61 is screwed into an electric socket. The switch is turnedon, whereupon the machine will operate continuously until the switch isturned off manually. V

It will be understoodthat the specific invention described may bemodified in formal respect, such as by the substitution'of equivalentsand that parts of the complete mechanism described may be used alone, orin other environments, without departingffrom the spirit or substance ofthe broad invention, the scope of which is commensurate with theappended claims.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters Patent is:
